1. He wants to influence the customary way of thinking and behaving that is shared by the

A. Organizational chart
B. Cultural network
C. Organizational structure
D. Organizational culture

Correct answer: A

Rationale: The correct answer is A: "Organizational chart." In the context of the question, the individual is aiming to impact the established patterns of thinking and behavior within a group or organization. An organizational chart typically depicts the formal structure of an organization, including roles, relationships, and reporting lines. By influencing the organizational chart, the individual can potentially shape the hierarchical structure and decision-making processes, thereby impacting the customary way of thinking and behaving within the organization. Options B, C, and D do not directly refer to the visual representation of roles and relationships within an organization, making them incorrect choices for this question.

2. What is the medical term for ingrown hair?

A. Folliculitis
B. Hirsutism
C. Pseudofolliculitis Barbae
D. Alopecia

Correct answer: C

Rationale: The correct answer is C: 'Pseudofolliculitis Barbae.' This term specifically refers to ingrown hairs commonly seen in the beard area. Folliculitis (A) is inflammation of the hair follicles, not necessarily due to ingrown hairs. Hirsutism (B) is excessive hair growth, unrelated to ingrown hairs. Alopecia (D) is hair loss, which is also not related to ingrown hairs. Therefore, 'Pseudofolliculitis Barbae' is the medical term specifically used to describe ingrown hairs in the beard area, making it the correct answer.

3. Why is it important to have control groups in scientific experiments?

A. To please funding agencies and research institutions.
B. To showcase the researcher's ingenuity and creativity.
C. To allow comparison and isolate the effect of the variable being tested.
D. To provide additional data points for statistical analysis.

Correct answer: C

Rationale: Control groups allow observation of what would happen without the tested variable, giving a baseline for comparison and isolating the specific effect being studied.

4. Which part of the respiratory system is responsible for gas exchange between the blood and inhaled air?

A. Trachea
B. Larynx
C. Alveoli
D. Pharynx

Correct answer: C

Rationale: The correct answer is C, 'Alveoli.' The alveoli are tiny air sacs located at the end of the bronchioles in the lungs where gas exchange occurs. Oxygen from the inhaled air diffuses through the thin walls of the alveoli and into the bloodstream, while carbon dioxide from the blood diffuses into the alveoli to be exhaled. The trachea (A) is the windpipe that carries air to and from the lungs; the larynx (B) contains the vocal cords and helps with swallowing; and the pharynx (D) is the part of the throat that connects the mouth and nasal cavity to the esophagus and trachea, but it is not directly involved in gas exchange.

5. What is the final stage of both mitosis and meiosis?

A. Interphase
B. Telophase
C. Cytokinesis
D. G1 phase

Correct answer: B

Rationale: Rationale: - Interphase (option A) is not the final stage of mitosis or meiosis; it is the phase before cell division where the cell prepares for division by growing and replicating its DNA. - Telophase (option B) is the final stage of both mitosis and meiosis. During telophase, the separated chromosomes reach opposite poles of the cell, the nuclear membrane reforms around each set of chromosomes, and the chromosomes begin to decondense. - Cytokinesis (option C) is the process of dividing the cytoplasm to form two separate daughter cells. While it occurs after telophase, it is not considered the final stage of mitosis or meiosis. - G1 phase (option D) is the first gap phase in the cell cycle, occurring before DNA replication. It is not the final stage of mitosis or meiosis.

6. Which phrase best describes the tone of the passage?

A. Humorous and lighthearted
B. Suspenseful and mysterious
C. Objective and informative
